Immediate context (±2 verses)

NASB95 (NASB95)

"20. Gather yourselves and come; Draw near together, you fugitives of the nations; They have no knowledge, Who carry about their wooden idol And pray to a god who cannot save. 21. Declare and set forth your case; Indeed, let them consult together. Who has announced this from of old? Who has long since declared it? Is it not I, the LORD? And there is no other God besides Me, A righteous God and a Savior; There is none except Me."

"22. Turn to Me and be saved, all the ends of the earth; For I am God, and there is no other. 23. I have sworn by Myself, The word has gone forth from My mouth in righteousness And will not turn back, That to Me every knee will bow, every tongue will swear allegiance."

"24. They will say of Me, 'Only in the LORD are righteousness and strength.' Men will come to Him, And all who were angry at Him will be put to shame. 25. In the LORD all the offspring of Israel Will be justified and will glory." (Isaiah 45:20-25, NASB95)

Setting

Speaker: YHWH, through Isaiah.
Audience: the Jewish people in (or facing) Babylonian exile, and through them, "all the ends of the earth" (the universal scope explicit in the text).
Location: Jerusalem (Isaiah's compositional setting); the prophetic horizon extends to the exilic / post-exilic context.
Time period: c. 740-680 BC for the historical Isaiah; the passage is in Isaiah 40-55 (the so-called "Second Isaiah" / Deutero-Isaiah section, which conservative scholarship maintains as authentically Isaianic prophetic material addressed proleptically to the future Babylonian exile).

Theological reading

The passage is one of the most explicit OT monotheistic claims AND the most-cited OT proof of Christ's deity by NT-NT-Christological transfer. Three claims:

Universal salvific call. Pnu elai v'hivvash'u kol-afsei aretz, "Turn to Me and be saved, all the ends of the earth." The salvation of YHWH is offered universally, not just to Israel.
Exclusive divine identity. Ki ani-El v'ein od, "for I am God, and there is no other." This is one of the most concentrated OT monotheistic statements. The four-fold ein od / ein zulati in chs. 44-46 is the climactic OT articulation of strict monotheism.
Universal worship oath. Bi nishbati… ki-li tikhra kol-berekh, tishava' kol-lashon, "I have sworn by Myself… that to Me every knee will bow, every tongue will swear allegiance." YHWH swears by Himself (the strongest possible oath, Hebrews 6:13-18) that the eschatological universal worship will be directed to Him alone.

The exclusivity claim

The passage's monotheistic framework is uncompromising. Isaiah 45-46 contains:

45:5, "I am the LORD, and there is no other; besides Me there is no God"
45:6, "I am the LORD, and there is no other"
45:18, "I am the LORD, and there is no other"
45:21, "there is no other God besides Me"
45:22, "I am God, and there is no other"
46:9, "I am God, and there is no other; I am God, and there is no one like Me"

The cumulative force is strict monotheism, not merely henotheism (Israel's preferred god among many) but categorical exclusivity (YHWH is the only God; other "gods" are nothing, 41:24, 29).

The NT use, Philippians 2:9-11

The verse is directly applied to Christ in Paul's Carmen Christi:

"Therefore also God highly exalted Him, and bestowed on Him the name which is above every name, so that at the name of Jesus EVERY KNEE WILL BOW, of those who are in heaven and on earth and under the earth, and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father." (Philippians 2:9-11, NASB95)

The Pauline citation is direct verbal-quotation of Isaiah 45:23 LXX. Paul takes YHWH's exclusive oath, to Me every knee will bow, every tongue will swear, and applies it to Jesus. The transfer is doctrinally seismic:

YHWH speaks in Isaiah 45: "I have sworn… that to Me every knee will bow."
Paul applies this to Jesus in Philippians 2: "at the name of Jesus every knee will bow… every tongue will confess that Jesus Christ is Lord."
The conclusion: Jesus receives the worship that YHWH explicitly reserved for Himself alone. Therefore Jesus is included in the divine identity of YHWH.

This is the divine identity Christology argument developed by Richard Bauckham (Jesus and the God of Israel, 2008): Paul does not merely identify Jesus as like YHWH; he identifies Jesus as included in YHWH's exclusive identity. The transfer of Isaiah 45:23 to Christ would be unthinkable monotheistic blasphemy unless Christ is YHWH.

The Christological-deity argument

The verse is one of the most decisive OT-NT Christological proofs:

YHWH swears by Himself that universal worship belongs to Him alone (Isaiah 45:22-23).
YHWH explicitly excludes all other recipients of this worship, "I am God, and there is no other" (vv. 21-22).
Paul applies this exact oath to Jesus (Philippians 2:9-11).
Therefore Jesus is YHWH, included in YHWH's exclusive identity. Anything less makes Paul a polytheist.

The pattern matches:

Romans 10.13, Joel 2:32 ("everyone who calls on the name of the LORD will be saved") applied to Christ
Malachi 3.1, YHWH coming to His temple applied to Christ
Hebrews 1:6, "let all the angels of God worship Him" (Deuteronomy 32:43 / Psalm 97:7) applied to Christ
Revelation 1:8, 17; 22:13, YHWH's "first and last" / "Alpha and Omega" titles applied to Christ

The covenant of Hebrews 6:13-20

The verse is also picked up indirectly in Hebrews 6:13-20, God's oath sworn "by Himself" (because there was no greater to swear by). Hebrews 6 develops the theology of God's self-sworn oath as the supreme guarantor of His promises. Isaiah 45:23's bi nishbati, "I have sworn by Myself", is the OT precedent. The unbreakability of the universal-worship promise is the point of the oath: God cannot lie, cannot go back on this word.

Apologetic significance

The verses anchor:

Strict OT monotheism, against polytheism, henotheism, dualism, ancient near-eastern syncretism.
Christ's deity, the most decisive OT-NT proof when combined with Philippians 2:9-11. Christ receives the exclusive worship YHWH reserved for Himself.
The universal scope of salvation, the gospel's universalist scope (offered to "all the ends of the earth") is grounded in YHWH's own self-revelation, not a NT innovation.
The eschatological universal acknowledgment, every knee and every tongue. This is realized progressively in the gospel's spread and consummated in the eschatological kingdom (Revelation 5:13-14; 7:9-12).
Anti-Watchtower Christology, Watchtower theology (and other unitarian / anti-Trinitarian readings) struggles with this transfer. JWs translate Philippians 2:11 as "every tongue should openly acknowledge that Jesus Christ is Lord to the glory of God the Father", but the OT background of Isaiah 45 makes the high-Christological reading inescapable.

Patristic / scholarly note

Justin Martyr (Dialogue with Trypho 65, c. AD 160) cites Isaiah 45:23 in Christological argument. Athanasius (Discourses Against the Arians I.42; II.23) develops the universal-worship-of-Christ argument extensively from Philippians 2 / Isaiah 45 background. Cyril of Alexandria (Commentary on Isaiah; On the Unity of Christ) develops the Christological reading.

The Reformation: Luther (Lectures on Isaiah, 1527-1530); Calvin (Commentary on Isaiah), both treat Isaiah 45:21-23 as foundational monotheism + Christological pivot via Philippians 2.

Modern conservative scholarship: Richard Bauckham (Jesus and the God of Israel, 2008), the most influential modern treatment, arguing that Christ's inclusion in YHWH's exclusive identity is the heart of NT Christology. Larry Hurtado (Lord Jesus Christ, 2003), independent corroboration of early-high-Christology pattern. John Oswalt (Isaiah NICOT, 1986/1998); Alec Motyer (The Prophecy of Isaiah, 1993), defend the strong monotheistic + universalist + Christologically-fulfilled reading. N. T. Wright (The Climax of the Covenant, 1991, ch. 4), extensive Philippians 2 / Isaiah 45 treatment.
